This invention relatesv to Jordan plugs, beater rolls or the like and more particularly to the method of mounting the barsin `such devices. Y l 'An important object of the invention is to provide a bar mounting of suoli character that the bar will be very firmly held in its seated position and at the same time may be lvery readily installed or removed.

In the Ordinary Jordan roll construction the bars are forced; into slots which'may or Vmay not have an undercut shoulder for the reception of a rib formed upon the sloten gaging portion of the bar. y

It is necessary that the bar fit very closel in the slot,` and that it be rigidly held when it is in seated position; Since the bars are of considerable length, installation thereof is a difficult matter` and after a period of use the removalV is even more difficult,l theV bar tending to rust andotherwise impact in its groove. ofthe present invention is the provision-of a construction ofthis character wherein linser-v 35 tion of the bar is facilitated 'by so constructing the same that the bar is loose iitting in its -groove .until it is practically'seated and thereafter has engagement with vthe wallsof the groove veryfirmly seating it so that there isno danger of its loosening. in use.y

AA. further and more speciiic object of the invention is to provide in a structure of this character a wedging action between the walls vof the groove and the groove-engaging pori tions of the bar which is not effective` until the bar is substantially seated.

These and other objects I attain bythe construction shown in the accompanying drawings wherein7 for the purpose of illustration,

40 I have shown a preferred embodiment, ofmy invention and wherein:

Fig. 1 isi a longitudinal ,sectional .view through a Jordan roll constructed in accordance with my invention; 1 p l Fig'2 isa section on line 2-2 of Fig. .1

Accordingly,v an important object when the bar isfully seatedas shown onthe solid lines of Figi; n

Fig. 3 is a similar section wlienthebar is partially seated as indicatedbythe dottedk lines ofFig.` 1;.and

Fig. Lis an enlarged sectional view through one ofthe bladesvwhen seated in yits groove. Referring now more particularly to the drawings, the numeral-10 generally designates the roll body havingthey kusual front and rear heads 11 and 12. :The body is longitudinally` grooved for the receptioniof vbars l'which, as it is well known to those familiar with the art, include'longandi short bars of j which the yformer-.is herein illustrated.y InV accordance with my invention the bar-receiving grooves are enlargedintermediate the ends thereofV as indicated at Mythe enlarge `ment roccurring'atone side of the groove and producing a downwardly Vfacingshoulder 15, whichj inclines downwardly and outwardly from the opposed wall of the groove. ShoulT der 15 is preferably spaced from both the the groove has upper andlowerparallel-sided' Iuppenand lowerends of the'grooye so that sections 16 .and 17'and an.` intermediate secltion vin which thefwalls areupwardly convergent. Thebottom 18 of this groove conyergesfrom end to end of the groove upon -1 thelowerfendof. thev enlargement. 'The Ybar 13 has upon its side face'arib upper surface as the under-cut shoulder-115l has to the Iwall of the groove. Y The bottom edge Lof the bar converges upon the lowerv face lhat/ ing the same angle to tliegbar face atits of this rib from end to end of the bar.' The hasl greater depth than the rib.' During the final seating .movement\,'however,' the bottom edge ofthe. bar comesr upwardly Vuntil they' upper face of the rib 19 comes into engagement Withrfthe sla-nting shoiilder Vl5. This 'causes the entirebar to .be Vvvedged transversely .so that the'iiat face of the bar isEV forciblyrseated against the -flat iace of vthe groovef'at the Same time the baris' `shifted v:radially and this radial shifting will cause a bindingY action tojb'e set up between the shoulder l5 andthefbottom ofthe groove.-

By this arrangement, Vthe bar can -be very -iirmlyheld and at the same time, vvlieii it is desired to'I remove the barit merely ,neces-.V sary to drive the bara distanceasuiiicieiitpto i neath which Athe Wooden strips 2l arranged between ladj acent bars'fflmay expand?- soi-that`r4 'thesejbars Will bel seciirelyheld against"acci 7 'dental' disengagement.
